Time to start riveting the ribs to the main spar
I numbered the ribs, 1 thru 15, with the #1 rib being the first one at the inboard end of the main spar. I removed the end outboard rib (#15) since it doesn’t get riveted on yet. To get enough room to get into position to rivet the #14 rib, I removed the #13 rib. The inboard (heavy) part of the main spar is resting on the work bench, held in place with some 2x4 blocks and some rubber matting.
